Here’s a transcript of Kapor and Hertzfeld’s talk at O’Reilly. Chandler is written in Python, which Hertzfeld says is three times faster to program in than Java, which is three times faster than C. Chandler uses wxWindows for its platform-agnostic interface framework. The Mac version uses native widgets, but the program as a whole doesn’t feel at all native to me. I do like the way you can click on an address component (such as a phone number) to edit it. There’s no annoying editing mode, like in Apple’s Address Book. Hertzfeld apparently likes browsers: every view in Chandler has a URL, and one of the “key concepts is that you can have multiple Views onto each data set.” Kapor says: “We’re not successful if we make commercial development impossible.”
